LITERATURE OF THE DAY. Sub-Tropical Rambles in the Land of the Aphanapteryx. By Nicholas Pike. New York: Harper & Brothers. The story of a bright and educated traveler is always a capital one, and Mr. Pike has done wonders for Mauritius, which would seem in itself to be one of the most deplorably dull and fatiguing prominences on the face of the sea. An enthusiastic botanist and naturalist, as well as an interested ethnologist, this lively observer relieves the monotony of a seemingly easy consulate and repulsive population by watching all the secrets of animated nature around him. It is a very bloodthirsty island that his fates have guided him to: everything bites or stings or poisons. When wading out into the sea for shells, Mr. Pike is attacked by "a tazarre, a fish something like a fresh-water pike," which comes right at him repeatedly, "like a bulldog," and is only subdued by being speared in the head with a harpoon. Creatures elsewhere the most evasive and timid are here found fighting like gladiators: the eels bite everybody within their reach--one of these combative eels caught by our author measured twelve feet three inches; the fresh-water prawns "strike so sharply with their tails as to draw blood if not carefully handled." The exquisite polyps and anemones, whose painted beauty our author is never weary of relating, have mostly poisoned weapons concealed under their flounces, and treat the naturalist who would coquet with them to a swelled arm or a lamed hand. Centipedes, scorpions and virulently poisonous snakes animate the land, while the shoals, where the natives declare there are "more fish than water," teem with every sort of man-eating shark, and with the cuttle-fish watching for his prey from each interstice of the coral-reef. The latter, often of immense size, are caught and eaten, both fresh and salt, some fishermen collecting nothing else: they dexterously turn the ugly stomach inside out and thread it on a string slung round the neck. The horror of the lobster for these cuttle-fish is something curious; and it affords a gauge for the sensitiveness of crustaceae (and incidentally an argument against those who maintain the greater reasonableness of fishing than of hunting on account of the lower organization of the prey) to learn that the lobster must not be taken to market in company with the cuttle-fish, "or the flesh will be spoilt before he gets there, the creature being literally sick from fright." Meantime, in the ooze which forms a connecting link between sea and shore lurks the mud-laff, indescribably hideous in shape, leprous-looking, slimy, and darting a greenish poison through the spines on its back. Treading on one of these, the poor naked fisherman is apt to die of lockjaw; and Mr. Pike's kitten, having its paw touched with a single spine, perished of convulsions in an hour. Some of the sea-carnivora, however, are so beautiful that one is ready to forgive their more or less Clytemnestra-like tempers.
